scription'fof the invention, such as will enable ethersskilledt inthe ant; to which it appertains to make and use the same.

The object of this invention is the eX- termination of the boll weevil and provides a machine which may be utilized for cultivating the cotton plants and at the same time Vapply an insecticide thereto for destroying 'the boll weevil which is so destructive to the cotton industry.

Other objects and advantages will be apparent and suggest themselves as' the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction `may be resorted to without departing from 'the spirit of the invention within the scope of the appended claims.

Referring to the accompanying drawings forming a part of the application:

Fi re 1 is a side view of a machine embodying the invention,

Figure 2 is a view similar to Figure 1, taken on line 2 2 of Figure 1,

Figure 3 is a top plan view of 'the machne, the handle-bars `and tank being omitte Figure 4 isa horizontal section on the line 4-4 of Figure 1, Y

Fi re 5 is a rear'view of the machine, the handlebars being in section,

Figure 6 is a sectional view on the line' 6-6 of Figure 1, Y I

Figure 7 is a sectional detail view on 'the line 7 7 of Figure 4, and

Figure 8 is a detail sectional view on line 8-8 vof Figure 1.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The machine embodies a plow beamland a plow standard A2 provided at its lower end with a shovel, blade or point 2.5, The ma=l that. ifmmafiv up@ a7 wher and; isi,

I'efed ba hanftlbarls 5.i mashed-I to. the 156erpoifion, tthe beamfl- A runner. @Imate With'the Wheel-4 te-,Suppart the beam 1. and maintain the same in a 'predetermined posi? tion- A -horzavtella disposal frame? i5 insecticide to a distributingv wheel 12 whichr is provided with bristles or feathers 13 or like material forptaking up the insecticide from the feedwheel 11 and supplying it to the young plants. The hanger comprises a vertically disposed U-shaped portion 8 and horizontal arms 9 which are laterally adjustably connected to the beam 1 by clips 9*. The frame 7 is vertically adjustable on the upri hts of the hanger.

A pul ey 14 is fast to the'axle of the ground wheel 4 so as to rotate with the lat- 14 with apulley 16 mounted upon a stub axle carried by a clip 16 on the beam 1. A drive belt 18 connects a kpulley 19 on thev shaft of the distributin wheel 12 with a pulley 20 ony the shaft o the feed wheel 11, thereby operating the latter. A pulleyv 23 rotatable-with the pulley 16 is connected by belt 24 of the wheel- 12, whereby to vdrive the distributing wheel in a counter-clockwise diter and a drive belt 15l connects the pulley to a pulley 25 fast to the shaftv atta'hi te' the baal-,11 1 by means atahaeeat 'A tank or reservoir 21 mounted upon the beam 1, 'contains the insecticide in bulk and supplies fthe same to the pan 10. The tank or reservoir 21'preferably consists of a jar or large bottle which is inverted and mount ed upon a base y26 and to the neck of which is attached a flexible tube 22 which Vextends into the pan 10, the insecticide in the latter forming a seal to preventrwaste and maintain a uniform level of the insecticide so long asthe reservoir 21 contains a supply to replace that removed from the pan 10 by the dis ensing mechanism embodying the feed whee 11 and distributing wheel 12.

In practice, the insecticide in liquid form is supplied to the reservoir 21 and passes therefrom throuvh the tube 22 into the pan 10, the level of tlie insecticide in the pan being determined by the relative position of the delivery @ed @,f #les ,tube 9 which .is sealed when the insecticide in the pan reaches the same. As the machine is drawn over the' field, the feed Wheel 11 and the distributing Wheel 12 are rotated, the wheel 11 supplying the insecticide to the distributing Wheel 12 which removes the same therefrom and' supplies it to the plants in the form of a Wipe or spray by reason of the rotation ofy the Wheel and the bristles or feathers 13,

around the periphery thereof. The hanger 8 forms a protector to the ldistributing Wheel anda support for the machine When at rest to prevent its toppling over laterally.

What is claimed is :Y

l. In combination with a support, a hanger extending laterally from said support and adjustable relatively thereto, a Vframe adjustable on said hanger, an insecticide-containing pan on said frame, a feed Wheel journaled on said frame and: operating in l'said pan, a rotary brush' journaled on vsaid frame and associated with the feed Wheel to receive the insecticide therefrom.

2. In combination With a support, a hanger extending laterally from said support and adjustable relatively thereto, a frame adjustable on said hanger, an insecticide-containing pan on` said frame, a feed Wheel journaled on said frame and operating in said pan, a rotary brush journaled on said frame and associated with the feed Wheel to receive the insecticide therefrom, a ground Wheel, and a driving connection betweenthe ground Wheel and said feed means and rotary brush. t In testimony whereof I ai'ix my signature.
